Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed August 30,1906. Serial No. 332,617.

To all whom it may concern:

Be it known that I, MARI ANUs CUMING, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Carving-Machine, of which the following is a full, clear, and exact description.

My invention relates to carving machines, and more particularly to a machine of this type particularly suitable for duplicating blocks, brims or curls upon which hats are formed and finished.

Among the several objects of my improvements are the following: 1. To provide a machine with upper and lower decks, the upper deck being used for supporting the block to be shaped, the model or pattern block being supported upon the lower deck; 2. To place the two decks in such position as to occupya com- "T'Lr paratively small floor space; 3. To provide various means for adjusting different parts so as to render the machine more efficient; and 4. To provide various constructional details and combinations of parts Whereby the work of the machine is facilitated.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a machine made in accordance with my invention and showing a pattern block and a working block in position to be operated upon; Fig. 2 is a side elevation of the same machine, showing it as seen from the left of Fig. 1; Fig. 3 is an enlarged fragmentary vertical section through the upper deck and its accompanying parts, and showing the means for clamping the work block in position upon the deck; Fig. 4 is an enlarged fragmentary vertical section through the lower deck and its accompanying parts, the pattern block being removed; Fig. 5 is a fragmentary section through the cutter shaft, showing the manner in which it is driven by aid of the belt and Fig. 6 is a fragmentary enlarged section showing the tracer 38 and the means for adjusting the same.

The stationary frame 6 supports the working parts. Pulleys 7 8, are rigidly mounted upon a revoluble shaft 9 and are used for transmitting power to the belt 10, the power being appliedto the pulley 8. A bracket 11 is mounted upon the frame 6 and carries rollers 12, the latter being supported by shafts 12.. A pulley 13 (see Fig. 5) is located between bearings 14 and is provided with a spline 15 which engages a revoluble shaft 16, the latter being provided with a spline-way 17 into which the spline 15 fits. This enables the shaft 16 to slide vertically with reference to the bearings 14 and the pulley 13, while permitting of the rotation of both the pulley 13 and the shaft 16. A bit or cutting tool 18 is secured by a clamp 19 uponthe lower end of the revoluble shaft 16. A cross bar 20 is provided with an enlarged portion 21 serving as an annular bearing and with a bolt 22 which enters a groove 22 encircling the upper end of the shaft 16. The shaft 16 is adapted to spin freely within the bearing 21 when driven by the pulley 13, as will be understood from Fig. 5.

The cross bar 20 is connected by cylindrical rods 23 with another cross bar 24, the rods 23 passing through fixed bearings 25 serving as guides therefor. The two cross bars 20, 24 being thus connected by the cylindrical rods 23 constitute together therewith a frame which is movable bodily in relation to the stationary frame 6. Mounted upon the cross bar 24 is a bracket 26 depending therefrom as shown at the left of Fig. 1. A link 27 is journaled upon the bracket 26 and is pivoted to a hand lever 28, the latter being journaled upon the frame 6 at 29. By manipulating the lever 28 the cage above-mentioned is raised or lowered at will.

The cross bar 24 is provided with an enlarged portion 30 having the form of a collar, and neatly fitting into this collar is a stem 31 carrying at its lower end a disk 32 and secured in position by aid of a bolt 33. By loosening the bolt 33 and turning the disk 32 the latter may be brought into any desired position in its horizontal plane, as will be understood from Fig. 6. The disk 32 is dove-tailed, and fitting into it is a slide 34 provided at its ends with ears 35 through which passes a threaded shaft 36. This shaft extends through the disk 32. As will be seen from Fig. 6, the operator by turning the shaft 36 can draw the slide 34 endwise in either of two directions.

, Rigidly connected with the slide 34 is a tube 37 located centrally in relation thereto and extending vertically downward therefrom. Mounted upon the lower end of this stem is a head 38, constituting a tracer and provided with a small stem 39 extending upwardly into the end of the stem 37 which is made tubular for this purpose. A pin 40 extends rigidly into the stem 37 and secures the stem 49 relatively thereto. A cross bar -41 is supported rigidly upon the frame 6-, and depending from this cross bar is a hook 42 journaled thereupon and adapted to engage a flange 43 in the cross bar 24. By this arrangement the cross bar 24 and other parts connectedtherewith may be temporarily supported upon the hook 42. The hook 42 is thus used whenever it is desired to suspend the movable frame, the machine being idle. Stationary waybars 45 are connected by a plate 46 which supports one end of a revoluble screw 47. This screw is provided with a handle 48 and with a journal neck 49 as indicated in Fig. 4. The way-bars 45 are provided with ways 50 which support a carriage 51, the latter being engaged by the screw 47 and movable thereby (see Fig. 4). This carriage is provided with a flat plate 52, above which is a large gear 53. This gear is flat upon its upper surface and constitutes a revoluble table.

@Projecting vertically from the upper surface of the gear 53 are bosses 54, and mounted upon the upper surface of the gear is a flat disk 55 which is connected rigidlywith the gear and consequently revoluble therewith. The gear 53 is j ournaled upon a pivot 56. Three spacing rods 57 are connected with the plate 52 and extend upwardly so as to support a horizontal plate 58. This plate is provided upon its under side with bearings 59 (see Fig. 3) which fit upon ways 60, the latter being provided with a brace 61 and connected integrally with the framework. The plate 58 is thus free to travel upon the ways 60 (see Fig. 2), and of course carries with it the rods 57, 66 and other parts connected directly with these rods. The plate 58 is provided at one of its edges with a lug 62 (see Fig. 1), which serves as a limiting stop for preventing excessive movement of this plate. A. large gear 63 is revolubly mounted over the plate 58 and meshes with a pinion 64, this pinion being rigidly mounted upon a journal neck 65 of a revoluble shaft 66. The journal neck 65 works in a bearing 67, which is integral with the plate 58 as indicated in Fig. 3. The large gear 63 is provided centrally with a bearing sleeve 68 which runs upon a hollow shaft 69. The latter is threaded internally and is engaged by a screw 70. This screw is provided with a handle 71. The bearing is shown at 72. A nut 7 3 is fitted upon the screw 7 0. Levers 74 provided with claws 75 are journaled upon the nut 73 and are tensioned relatively to each other by a spring 76, see Fig. 3. The levers 74 normally spread apart, occupying the position indicated in Fig. 2, and when pressed slightly toward each other they of course tend to diverge. A revoluble plate 77 is mounted rigidly upon the large gear 63 and slightly overlaps the pinion 6 1. When this pinion is turned the plate 77 turns also, but at a relatively slow rate.

A pinion 78 fixed upon the revoluble shaft 66 meshes with the gear 53 and serves to rotate the same. A miter-gear 79 is mounted upon the revoluble shaft 66 and meshes with another miter-gear 79, the latter being rigid upon a revoluble shaft 80. The hand wheel 81 is connected with this last-mentioned revoluble shaft and is used for turning the same. By rotating the hand wheel 81 motion is communicated through the mitergears just described and thence through the pinions 78 and 64 to the lower and upper gears 53 and 63 respectively. In this manner the plates 55 and 77 are caused to turn synchronously in either direction, according to the direction of movement upon the hand wheel 8]. Mounted upon the cross arm 20 at the top of the machine is a fork 82 to which is journaled a lever 83. A link 84 is pivotally connected to the framework and is pivoted at its upper end to the lever 83 by aid of a pin 85. Weights 86 are slidably mounted upon this lever and are secured thereto by means of set-screws 87. The model or pattern block is shown at 88 and the work block at 89. The weights 86 are adjusted so as to balance the movable frame above described. The work block 89 is provided with a central aperture 89 as indicated in Fig. 1.

My invention is used as follows :-The pattern block 88 is placed upon the flat disk 55 and secured firmly thereto in position. For this purpose the bosses 54 may be employed as anchorages. Preferably these bosses fit neatly into apertures made within the block for the purpose. The Work block 89 is now pushed downwardly over the levers 74 (see Figs. 1 and 3), which serve to center the block. The hand wheel 71 (see Fig. 3) is next turned and this causes the screw to draw the nut 73 slightly downward. The claws now spread apart for the action of the levers 7 l and grip the internal surface of the block 89 so as to hold this block firmly downward upon the revoluble table 77. The pulley 7 drives the belt 10 as above described and thus communicates a rotary motion to the pulley l3 and the revoluble shaft 16. The cutter 18 is therefore ready to cut the work block 89 as soon as it is brought into engagement therewith. the hand lever 28 and presses it slightly. The tracer head 30 is thus brought into engagement with the upper surface of the pattern block 88. The cutter 18 cuts into the work block 89 to a degree commensurate with the height of the tracer head 38 above the flat surface 55, or in other words, to the extent permitted by the thickness of the pattern block 88. The operator by turning the hand wheel 81 in either or both directions turns both the pattern and the work block at will. By having the vertical motion of the bit 18 constantly under control of the hand lever 28 and by having the rotation of the pattern t1ld WOllC block also under control of the hand wheel 81, it is clear that the operator can cause the cutter 18 to shape the work block according to the conformity of the pattern. In order to draw the revoluble tables 77 and 55 toward the front of the machine, or to cause them to recede in the opposite direction, the operator merely turns the handle 48 to the right or to the left according to the general change of position desired in the revoluble tables.

It will be noted that by turning the threaded shaft 36 (see Fig. 6) and thus adjusting the slide 34 the radial distance of the tracer head 38 from the center of the block 89 may be controlled. brim left upon the work block 88 may be controlled at will.

As may be readily seen from the above, I employ a frame movable vertically and controllable by means of a hand lever for the purpose of carrying the cutting mechanism, and I also employ a sub-frame n'ovided with upper and lower decks, each deck being provided with a turn-table.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
